There is a lot of good info on the dash carrier here. I just finished one on my 69. I must say being a maintenance tech in a auto plant that the process of manufacturing has come a long way. I decided to buy a carrier rather than ship out. My carrier was just to brittle from time and I guess the summer heat. Anyone doing this yourself just take your time. Take pictures before and just try and have fun with it. I had to cut out for clock, tach, and defroster switch and that made mine a little harder but now it's on the next project.
